IPC: H01L21/321
Filed: 1990-04-13
Abstract: PURPOSE:To strengthen the adhesive forces of both films of an oxide film and a metal oxide film identical with the lowest metal layer of a base electrode and to contrive the improvement of the reliability of a semiconductor device by a method wherein a composite oxide film consisting of the elements of both oxide films is formed on the contact surface of the oxide film with the metal oxide film. CONSTITUTION:A silicon oxide film 2 is formed on the whole surface of an Al wiring 1 in a thickness of 2mum or thereabouts. After that, a chrome oxide film 3 is formed on this film 2 in a thickness of 0.5mum or thicker and is used as an insulating film. After that, the films 2 and 3 are selectively removed and one part of the surface of the wiring 1 is made to expose. Then, a laminated film consisting of three layers of a Cr layer, a Cu layer and an Au layer is formed on the whole surface and a base electrode 5 is formed by patterning the laminated film. Then, a thick film photoresist film is formed, a part, which correspond to a scheduled bump electrode formation region, of the photoresist film is selectively removed, is made to open and thereafter, a Pb-Sn film is deposited. The photoresist film is dissolved and removed, the Pb-Sn film is left only on the part to correspond to the scheduled bump electrode formation region and a wetback (a heat treatment) is performed to form a semispherical bump electrode 6.

Title: Image processor
Inventor: IKEDA SHINGO
IPC: H04N19/423
Filed: 1993-03-31
Abstract: PURPOSE:To make an error inconspicuous on a screen after decoding even when the error appears halfway. CONSTITUTION:A memory circuit 3 and a memory control part 4 divide an inputted image signal S1 into blocks consisting of plural pixels. An orthogonal transforming process part 5 performs the orthogonal transformation of the data in the divided blocks. Further, when the orthogonally transformed data are quantized and encoded to variable length by selecting plural divided blocks so as to obtain a code quantity in a certain range, the position of an (n)th selected block among blocks selected for fixed-length encoding is made to approach the periphery of the screen as (n) becomes larger. Consequently, if the error occurs before decoding, the generation of the error is made frequent at the periphery of the image to make the error visually inconspicuous.
